Description

Technical Field

[0001] The present invention relates to the technical field of vehicle-mounted water pumps, and in particular to an integrated water pump cover structure with filtering effect. Background Art

[0002] With the development of economy, the automobile industry has developed rapidly. As the performance of automobiles is developing towards safer, more reliable, more stable, environmentally friendly and energy-saving directions, in order to ensure the stable operation of automobile powertrains, it is necessary to equip complete actuators. Therefore, various actuators with motors are widely used in automobile powertrains, including hydraulic actuators, gear selector actuators, brake assist, etc.

[0003] In order to ensure the cooling and lubrication of various engine components, an electronic water pump is needed to provide power for the oil circulation. The electronic water pump is powered by an internal motor to drive the impeller to drive the oil circulation to cool and lubricate the relevant components. In order to ensure its lubrication and cooling effects, the current water pump usually does not have a filtering structure at the water inlet pipe. The ordinary filter screen brings a large flow resistance when the water flows through, which is easy to generate noise and the service life will be greatly reduced. Therefore, it is necessary to improve it. Summary of the invention

[0004] The present invention provides an integrated water pump cover structure with a filtering effect, which is easy to install, can filter impurities in the water passing through a water inlet pipe, better guide the flow direction of the liquid, has good overall structural stability, low noise, and better use experience; it solves the technical problems existing in the prior art that the water pump in the current vehicle-mounted engine has no filtering structure when coolant flows in, impurities enter the water pump and easily cause damage, reducing the service life of the water pump, and the flow resistance and impact are large when the water flows, and the noise generated is greater.

[0005] The above technical problems of the present invention are solved by the following technical solutions: an integrated water pump cover structure with filtering effect, including a water pump body, a central rotating shaft is arranged in the water pump body, an impeller is arranged at the center of the top of the water pump body, a water pump cover is arranged on the top of the water pump body, the water pump cover is integrally injection molded, the integral body on the water pump cover is injection molded with an inlet pipe and an outlet pipe, and the inlet pipe is integrally injection molded with a deep concave filter extending to the inside of the water pump, and the surface of the deep concave filter is provided with a plurality of dense leakage holes. When working, the motor shaft drives the impeller to rotate, and the water flows in from the water inlet pipe. When the water passes through the deep concave filter in the water inlet pipe, the leakage holes on the surface of the deep concave filter can effectively filter the impurities in the coolant, and the deep concave structure can effectively reduce the flow resistance, and the water flows out from the outlet pipe under the action of the impeller.

[0006] Preferably, the deep concave filter is made of metal, and the diameter of the deep concave filter gradually decreases from top to bottom. The deep concave filter can effectively filter impurities in the coolant, and the deep concave structure can effectively reduce flow resistance. The deep concave filter made of metal has good wear resistance and is not easy to wear and produce debris.

[0007] Preferably, the bottom of the deep concave filter is integrally formed with a matching seat, a sliding bearing is fixed in the matching seat, and the central shaft extends into the sliding bearing for matching. The matching seat at the bottom of the deep concave filter can not only hold the central axis, but also reduce the structural design for fixing the central axis.

[0008] Preferably, the ends of the water inlet pipe and the water outlet pipe are integrally formed with an anti-dropping protrusion that is smoothly raised outward. The outer diameter of the anti-dropping protrusion is larger than the diameter of the water inlet and outlet pipes, and the function of the anti-dropping protrusion is to more firmly perform interference fit with the matching structure to prevent it from falling off.

[0009] Preferably, the outer walls of the water inlet pipe and the water outlet pipe are integrally formed with limiting protrusions, which are used to facilitate the limiting and positioning of the water inlet and outlet pipes during matching and installation.

[0010] Preferably, a spiral water channel is integrally injection molded in the pump cover of the water pump. The spiral water channel has small flow resistance and impact, and the noise generated is small, which can bring a better use environment.

[0011] Preferably, the outer wall of the water pump cover is integrally injection molded with a plurality of reinforcing ribs, which are radially distributed and function to increase the strength of the overall structure.

[0012] Preferably, a sealing installation groove for installing a sealing ring is provided on the inner side of the water pump cover. An annular sealing installation groove is provided on the inner side of the water pump cover to facilitate the installation of the sealing ring and ensure the sealing between the water pump cover and the water pump body.

[0013] Therefore, the integrated water pump cover structure with filtering effect of the present invention has the following advantages: it is easy to install, can filter impurities in the water passing through the water inlet pipe, and can better guide the flow direction of the liquid through the deep concave filter screen and the spiral waterway. The overall structure has good stability and low noise, and the experience brought in actual use is better. BRIEF DESCRIPTION OF THE DRAWINGS
